CHAPPAQUA - The principal of Horace Greeley High School will resign at the end of the month, the latest administrator in a string to leave the district in recent years.

Citing personal reasons for his exit, Principal Robert Rhodes' resignation comes after a paid leave of absence, also for personal reasons, was approved by the Chappaqua school board on June 13.

But on Friday, schools Superintendent Christine Ackerman announced in an email that Rhodes would resign.

Rhodes became principal at the 1,300-student school in 2012. His tenure included the controversy surrounding former Greeley drama teacher Christopher Schruafnagel, who resigned and was charged in 2015 with sexually abusing several students.

Schraufnagel pleaded guilty to the charges and now faces seven civil lawsuits.

Horace Greeley Assistant Principal Laura Dubak was approved earlier this month to serve as acting principal in Rhodes' absence. But Wednesday she announced that she was leaving to become an assistant principal at nearby Byram Hills High School.

Dubak will stay on as acting principal at Greeley through the end of the month.

"While I am excited about the change and new opportunities at Byram Hills, it is bittersweet to think about leaving a community of passionate and dedicated students, involved and passionate parents, and an incredibly dedicated faculty and staff at Greeley," Dubak said in her note to the community.

Sex-abuse scandal

The resignations are among several that came following a sex-abuse scandal that has shaken the community in recent years,.

The turnover started with the ouster of former Superintendent Lyn McKay in the fall of 2016. Eric Byrne, who was Chappaqua's assistant superintendent for curriculum, became acting superintendent after McKay's resignation.

Schraufnagel and several district officials are also named in seven civil lawsuits that are still pending in state and federal court.

Proposed successor former assistant

Ackerman, the superintendent, addressed the recent departures in an email to the school community late Friday morning. The schools chief, who is wrapping up her first year in Chappaqua, is recommending to the board that Andrew Corsilia be Rhodes' replacement starting Aug. 1.

"Mr. Corsilia's strong background as a secondary (school) leader and his understanding of our high school will provide the (necessary) stability for our district as the high school rebuilds its administrative team," Ackerman wrote.

Corsilia is the principal of Seven Bridges Middle School, one of the district's two middle schools, and has worked in Chappaqua since 1998. Before becoming principal at the middle school, Corsilia was an assistant principal at Greeley and an English teacher before that.

During his time as the high school's assistant principal, Corsilia conducted Schraufnagel's professional performance reviews in 2013, 2014 and 2015, which were obtained by The Journal News/lohud through a Freedom of Information Law request, but were almost entirely redacted.

Corsilia is also cited in court documents as the person who reported that a student approached him on June 14, 2015, about an alleged sexual relationship with Schraufnagel.
